At all outlets (dimmed / undimmed) results in the same error image:
The Philips LED lamp turns off after about 15-30 minutes of operation for a short time (about 2 seconds) and back on. The Ausschaltrhythmus can then be partially faster. Particularly striking is the behavior when the lamp is operated at full brightness with a dimmer. If the lamp is dimmed to about 70-80% brightness is no longer occurs, the behavior.
Unfortunately, the lamp is thus not usable. Who wants to constantly sit at dinner for a short time in the dark.
